Hi folks, I have a problem with ros-diamondback-turtlebot-robot installation. I'm planning to assemble something like turtlebot described on ros.org, but instead of netbook, I'm going to use TrimSlice(http://trimslice.com/web/), which already has Ubuntu. I was following this instructions http://www.ros.org/wiki/Robots/TurtleBot/diamondback/Robot%20Install but when I tried to install I got problem that system can not find package ros-diamondback-turtlebot-robot. I've checked /etc/apt/sources.list.d/ros-latest.list many times and tried different mirrows but got same result. When I tried to perform same steps on virtual Ubuntu 10.4 I was able to install everything how it suppose to be. But if I'm trying to do it from TrimSlice I got this problem with unavailable package. I use Ubuntu Natty for Nvidia tegra, may be this architecture is a problem? Any ideas how I can solve this issue? I'm a newbie with ROS, and have limited experience with Linux, so a few cents from you guys can help me a lot. Thanks. -Roman.
